In the drawings, Figure 1 is a vertical section of a bath-tub and my'improved fitting attached. Fig. 2 isa detail vertical section of the entire fitting, withthe sup ply, overflow, and waste-pipes connected thereto. Fig. 3 is an elevation of the entire fitting detached from the tub. Fig. 4 is a cross-section of the chamberB and waste-duct F through the valve rock-shaft G. Fig. 5 is adetail vertical section of the chamber B and connections, showing a modification of my device in respect tothe cut-off valve. Fig. 6 is a crosssection of same through the rock-shaft G. Figs. 7 and S are, respectively, verticaland cross sections of the chamber B, showing another modiiication of the same feature.

A is the bath-tub, having a water supply and discharge orifice a located at the bottom.

B is a ttingwhich comprises the flange B at the top, adapted to bear against the under sideof the bath-tub aboutthe water-orice and make a Water-tight junction therewith by means of packing, which maybe inserted between the tub and fiange. Said fitting comprises, further, the body portion B2, the overiiow eduction-passage B3, the supply-passage B4, and the waste-outlet passage B5. Said 'fitting is open from top to bottom, the top opening into the bath-tub through the waterorifice thereof and the bottom opening into the removable pocket E, which is preferably made of glass andclamped onto the fitting B lby suitable coupling, as Ef, making a watertight junction by means of packing inserted between the pocket and the lower end of the fitting B.

F is a thimble or sleeve which has at the upper end the iiange F', which is perforated and of sufficient diameter to overlap the water-orifice a of the bath-tub and bear upon the margin of said orifice, and at the middle point is eirteriorly threaded and screwed in to the interior boss B of the fitting B, and passes entirely through and protrudes downward intothe pocketE. The flange F of this thimble constitutes the strainer, and its longitudinal duct constitutes the induction portion of the waste-passage from the tub. This wastepassage is adapted to be open ed and closed by a valve, which closes the mouth of one of the orifices of the lower chamber. The orifice .closed may be the mouth of either an induction or eduction pipe. j

In Figs. 1, 2, and 4 I show a valve G at the lower end of the duct F, opened by the pull M, attached to the lever-arm G. When the tub is empty, it is held up against the lower end of the duct by the'weight of the pull-rod resting upon it independentlyof any locking device on the pull M for locking'it in such position, and any back-pressure of waterv seats it firmly, and thereby prevents any foul Water risingfrom the sewer or any gas generated in the trap from entering the tub.r

In order to hold the Valve against the mouth of the waste-duct when the tub is filled, and also to hold it away from said mouth when the tub is to be emptied, any locking device may be employed, as the notched plate M', Secured to the pull-rod and lodged on a projection m on the edge of the tub. Preferably, however, I employ a valve N, seatingv against the mouth of the outlet-passage B5, as shown in Figs. 5 and 6, in form a cylindrical segmentto fit against the walls of the chamber, Secured to two `guides n n, which fit within the outlet-passage B5, pass through the valve, and around the ductFin a groove in its outer surface, in which they run, and by which means the valve is kept from sagging or the guides from binding in thepassage B5. They unite in the stem n,which is provided with a 'longitudinal aperture through which the free end of the lever-arm G', attached at its other end to the rock-shaft G2, passes and operates the valve by the movement of the valve-rod. p

A modification'of this device is shown in Figs. 7 and 8, in which the guides n n are pivoted on arms n2 n2, which pass around the duet F and are attached to the rock-shaft- G2 by the lever-arm G. Either of these three devices obviates the necessity for a rubber stopper and attendant chain in the tub atthe upper end of the duct F. The valve shown in Figs. 5, (i, 7, and S will be held shut by the pressure of the water in the tub when it is full, and is opened by the pull M, attached to the rock-shaft, and can be locked open or sluit by any suitable device on the pull-rod. A boss BG, constituting a horizon tal partition or diaphragm, is located between the level of the supply-duet and the overtlow eduetionpassage on the upper side and the waste outletpassage on the lower side, so that the thimble F constitutes a seal from the bathtub past the first-mentioned upper passages to the said lower passage, so that water entering said thimble from above from the tub cannot pass into the overtiow eduetion-passage or into the supply-passage, but must escape bypassing beyond the diaphragm B, and so has access only to the passage which is below said diaphragm. Furthermore, since said thimble terminates in the pocket E, which is below all the passages communicating with the fitting B, there is formed in said pocket a t-rap which shuts off communication for sewer-gas from the waste-pipe into the bath-tub.

H is the stand-pipe, having two passages H and H2, the former being a continuation of the overow eduetion-passage B3 and the latter emptying directly downward into the waste-pipe K, and thence to the sewer. Said passages lll and ll2 unite above the partition or wall 71,2, and at the upper end the standpipe H`tcrminates open, adapted to be cennected to a suitable Ventilating-pipe.

To the supply-passage B4 is connected the supply-pipe J, andthe waste outlet-passage B5 is connected tothe waste-pipe K, and thence to the sewer.

The operation of this device is as follows: Tater being admitted to the supply-pipe enters through the passage B4 to the cavity of the fitting B around the thimble F, and rises through the strainer or flange F into the bath-tub. The valve G closing the direct waste-passage F, the water will rise in the tub,and at the same timepassing outthrough the overiiow eduetion-11 assage B3 will rise in the stand-pipe 1l until the height of the partition-wall is reached in the pipe and tub, and thereafter the water entering through the supply-pipe will ow out over said partition through the passage H2 to the sewer. The supply having been cut ott and the tub put into use, when it is desired to empty the same, the valves G or N being opened, the water in the tub will pass out through the duet F (which is a direct waste-passage down into the pocket E) and up and out through the waste outlet-passage Simultaneously with this outfiow through the tub the water from the passage H of the stand-pipe I-l will re-enter through the passage B3 and rise through the strainer F', preventing the accumulation ot any filth thereon, which might otherwise be lodged by the outtiowing stream through the direct waste-passage of the thimble F, and will thus join the waterin the tub and fiow out through said direct wastejpassage, so that when the tub is finally emptied all passages will be fiushed clean, except there should be heavy matter whichhas passed out from the direct waste-passage in the thimble F and be lodged in the pocket E. Any such matteil thus accumulated in the said pocket will be readily discernible, the pocket being ot' glass, and the coupling E can be removed, the pocket E detached, and such matter removed. It will be observed that the direct waste-passage from the tub is, as has been stated, through the thimble F, and also that the annular space surrounding the thimble above the boss BG is a part both of the over- Iiiow eduetion and the supply induction passages; also, that there can be no com mimication from the overtiow or from the supply to the direct waste-passage through the duct F except that which occurs by the fiow back and through the strainer F into the tub, and the result ot' these relative positions of the several parts is that by no possibility can any water, except that from the overflow-passage, which is always clean water derived directly from the supply,be retained in the fitting in such position that itmayenter the tub with supply-water, and, as above IOO pointed out, the strainer through which the supply passes is washed clear, and whenever the tub has emptied will not therefore contain foul matter to contaminate the supply when next thereafteradmitted. Considering the trap in the pocket E in its relation to the duct B3 and the descending portion of the waste-pipe, it will be seen that the duet B3, having communication with the air at the upper end of the stand-pipe Il, will effectually prevent the possibility of the trap being siphoned out and emptied while the waste-pipe is filled with the outowing stream. This function is important, because the duct F is thereby rendered certain to be water-sealed at its lower mouth, since the trap will always be kept full of water; also,inasmuch as the no possibility of forcing past the water in the trap E and entering the room.

I do not herein claim, broadly, the combination or arrangement of the parts by which the supply is admitted through the overflowpassage directly to the bowl in the vicinity of but without passing through any portion of the waste-passage, because I have claimed `that matter in my pending application, Serial No. 255,457, originally filed as Serial No.
